perf tools: Update documentation info about quipper
The existing link is outdated. The most recent quipper code can be found at the new URL. Committer notes: Quipper is a C++ parser that can be used to convert from a perf.data file to and from a protobuf, a Chromium OS facility.

quipper
The quipper C++ parser is available at
-https://chromium.googlesource.com/chromiumos/platform/chromiumos-wide-profiling/
+https://chromium.googlesource.com/chromiumos/platform2
+
+It is under the chromiumos-wide-profiling/ subdirectory. This library can
+convert a perf data file to a protobuf and vice versa.
+
Unfortunately this parser tends to be many versions behind and may not be able
to parse data files generated by recent perf.
